heat is really half of friction
Friction produces heat.
Ice has little friction. Sandpaper has lots of friction.
Heat from friction can be found using the formula: heat = frictional force × distance. When two objects rub against each other, friction generates heat due to the resistance encountered. The amount of heat produced is directly related to the force of friction and the distance over which the friction acts.
Mainly heat and static electricity are produced by friction.
Yes, heat can be produced by the friction process. When two objects rub against each other, the friction generates heat due to the resistance between their surfaces. This can be observed when rubbing your hands together quickly, causing them to warm up due to the heat generated by the friction.
heat friction
Friction produces thermal energy, also known as heat energy. This is because as objects rub against each other, the kinetic energy of their movement is converted into heat energy due to the resistance of friction between the surfaces.
As a result of friction, kinetic energy is commonly lost; the result is heat energy.
With any moving fluid, there will be a little bit of friction, which would increase temperature. But the heat could be dissipated to the surroundings just as fast as the friction is generating the heat, depending on the type of fluid, speed, and configuration of the pipe. For your question - the faster the flow, the more friction and therefore heat.
Heat
You can not have friction less joint. Even in any mechanical unit, you can not have frictionless movement. By the way, hats off to the great scientist, Sir Issac Newton. He could imagine about the law of motion, in which there was no friction.
Friction causes heat. Heat is a source of energy.
